The morning is perfectly beautiful, but not enough.
It is only the half, it is only the part. The sun has to rise in the evening too, then life is total. One has to rejoice not only in life, but in death too, then life is total. One has to rejoice not only in love, but in aloneness too, then the dance is complete.
That's why I say I have seen the sun rising in the evening: the circle is complete. The evening is the other side of the morning. If the sun rises only in the morning, then you will become attached to the morning, and when the evening comes you will not be able to say yes to it. And the evening is coming. If the morning has come, the evening is coming. If you were born, you will be dying. The sun has to rise in your death too.
You have to die like a Buddha with a song in the heart, with a yea-saying. You have to die like a Krishna -- still playing on his flute. You have to learn that peaks are beautiful, but so are valleys; and the darkes night also has a full moon in it.
That is the meaning of the sun rising in the evening. It has an immense significance, it has a great message for you. I am saying that life in all its colours is beautiful, that nothing bas to be denied, rejected; that nothing has to be destroyed; that nothing has to be renounced; that all has to be accepted in great joy, in great gratitude, and then the sun rises in the evening too. And the beauty of it is immense, because everybody knows thesun that rises in the morning, and very few know the sun that rises in the evening. The moment you can see the sun rising in the evening, you have become a Buddha. Then all is good. When all is good, then all is God.
